This comparative case series presents 16 consecutively placed and temporized immediate implants in the maxillary esthetic zone. The implants have a novel, inverted body-shift design, intended to achieve high levels of primary stability via the tapered apical portion. The coronal narrow cylinder provides greater space between the implant platform and facial socket wall and adjacent teeth/implants, allowing a greater opportunity for augmentation. The restorative platform also features a subcrestal angle correction, which facilitates screw retention. The wider, facial platform-shift thus creates more room for augmentation via dual-zone bone grafting and the application of a dermal allograft, which yields greater soft tissue thickness after initial healing. This case series aimed to evaluate soft tissue thickness and compare the results to two previously published cohorts where implant design served as the only variable between groups.
